it was a tourfor work i was stationed in south korea for a year and several people in my unit got sent up there to walk around and check out the border security is incredibly tight when we approached the border we werent allowed to point or make any gestures at the north korean soldiers and we were definitely not allowed to attempt to talk to them it was insanely creepy having them stand only a few feet away from us outside the windows and just silently stare i didnt witness it but some american guards told me that whenever any black people visit the north koreans will whisper nigger nigger nigger to attempt to get a rise out of them but again i cant confirm if this is true or not
